BOTTLE CLOSURE.

Specification of Letters Patent.

Patented June 12, 1906.

Application filed August 1,1905. Serial No. 272,244.

To all whom it may concern:

Be it known that I, HENRY S. BREWING- TON, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Im rovements in Bottle-Closures, of which the ollowing is a specification.

My invention relates to an improvement in bottle-closures, the object of my invention being to provide a closure which will hermetically seal the receptacle and when placed in the mouth of the bottle will not strain or break the mouth of the bottle, due to the pressure of the expanding-tool used in securing the closure in the bottle.

My invention consists of certain other novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanfying drawings, Fi re 1 is a sectional view 0 my inventlon p aced in the mouth of a bottle before sealing. Fig. 2 is a similar View showing the closure sealed.

A represents a bottle-neck, and 1 is the cap or closure. The cap, or closure 1 is made in the form of a cup, and its upper edges 2 are turned over and lie parallel with the cap. A suitable packing 3, of rubber or some other suitable elastic material, is placed between the bottle-neck and the side of the cap or closure, which when the cap is pressed down will form an air and liquid tight sealing contact.

When the cap or closure is laced in the bottle-neck, the flanged edges 0 the cap rest upon the shoulder 4 of the bottle-neck, and an expansion-tool of any suitable shape or design is pressed against the flanged edges 2, which forces the edges flat on the shoulder 4, thereby forming an air and liquid tight sealing means.

It will be seen from the foregoing that I have provided a sealing means which is far superior to any now on the market, as I am enabled by my invention to provide a cap which will avoid the strain or pressure caused by the expansion-tool in placing the cap, and one which will not injure the lining of the bottle-neck, Whereas in the caps now in use they are forced against the lining of the bottle-neck by the expansion-tool, and it often cracks, chips, or injures the bottle neck to such an extent that it will leak or so break the bottle that it cannot be used, and the breakage of the glass becomes quite an item. In my invention I have formed a ca or closure which will obviate all these difli culties and one which can be easily and cheaply made, and it will be readily seen instead of the cap or closure'pressing against the lining of the neck all of the pressure is on the shoulder 4.

It is evident that other slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit inyself to the exact construction herein set forth; but,

Having fully described my invention, what I do claim as my invention, and desire to secure by Letters Patent, is

1. As an article of manufacture, a bottleclosure having a depending flange adapted to be pressed outwardly whereby to form a sealing contact, the body portion provided with a suitable packing.

2. In a bottle-neck having a shoulder and groove formed therein, a cap or closure to fit the bottle-neck having a depending flange, a packing between the bottle and the body portion of the closure, said flange adapted'to be ressed against the shoulder and groove to f drm a sealing contact.

3. In a bottle-neck having a shoulder formed therein, a cap or closure to fit the bottle-neck, and downwardly-extending flange on the closure, a packing between the bottle and the body of the closure, said flange adapted to be pressed against the shoulder to form a sealing contact.

In testimony whereof I afliX my signature in presence of two witnesses.

HENRY S. BREWINGTON.
